Dune-flood interactions

The pathological geomorphologists have been running a series on dune-river interactions recently, so I wanted to add this most recent TERRA image of the Queensland floods. The floodwaters in the Diamantina (top) and Coopers Creek (above centre) sections have now reached the longitudinal dunes of the Simpson desert. The full image has 250 meter pixel size, so it is easy to see individual dunes (which are generally a few hundred meters across the base and a few to tens of km apart). You will have to click the link for super high res goodness and detail- clicking the image only gives a medium resolution image.
These images are updated daily (weather permitting), so you can hop backwards and forwards to measure the progress of the flooding over the past month or so.
